Auroracoin has become the 4th biggest crypto-currency measured in market capitalization. How can an as-yet unreleased coin have market value if it's not available for exchange (either for fiat or for another crypto-coin) anywhere??? In fact, save for the storage accounts of its creator, noone has an Auroracoin yet. So whence comes its valuation and thus its market cap???
As much as I admire the stated intentions of Auroracoin's creators and their ingenuity for turning stuff traditionally seen as BAD (premining, universal and compulsory registration for all citizens) into GOOD, this market cap point makes me a bit suspicious.
